  Does JVM maintain a cache by itself? Does the JVM allocate objects in heap? Is this the OS heap or the heap maintained by the JVM? Why  

yes the JVM maitain a cache by itself.No it allocates the objects in stack ,in heap on references .Heap maintained by the JVM because

every time the JVM should not use objects directly it uses only references that's why the heap maintained by the JVM

Yes, the JVM maintains a cache.

It creates the Objects on the HEAP, but references to those objects are on STACK.

JVM maintain the cache itself.

About the object,
For Each Object JVM Allocate Memory for that Object in Heap.
And starting mem-location is store in stack for referance for that created object.

The JVM's heap stores all the objects created by the executing java program.

Stack stores the object references.

Reference value stors on stack and objects stores on heap

The stack contains of method arguments and local variables (ie. Local variables are only primitive types and references)

Everything else on the heap (instance members)

There are two kinds of memory used in Java.
These are called stack memory and heap memory.
Stack memory stores primitive types and the addresses of objects.
The object values are stored in heap memory.
An object reference on the stack is only an address that refers to the place in heap memory where that object is kept.

Yes the JVM itself maintain the cache and the heap and the all the primitive type and objects are stored in a heap and the reference to all are stored in stack

No,

JVM uses two memories

1) heap

2) stack

JVM creates objects on heap, but references to that object are on stack.

No.

JVM reserve the memory space in heap for objects. But the Stack holds the reference of the object.

This Heap is maintained by the JVM. So that, the JVM's Garbage collector can watch the application stack and clear the Heap memory.

Yes, It is...
The Java runtime system stores information in two separate parts of memory: the stack and the heap.
The heap stores all objects and all static variables.
The stack stores all local variables of methods (and parameters of methods are just local variables).

yes, JVM maintain a cache itself. JVM always create object in the heap memory area, and referance is stored in the stack.
yes, this heap maintained by JVM because when we run the application at first JVM send request to the OS for allocating the memory to execute the application and after the execution JVM release the memory.

yes java maintain a cache by itself.
as we know that java is platform independent. but jvm is platform dependent. but java byte code can be run in any platform. when java is install, jvm takes it's operating system as which it is installed. so when we compiled a program it will allocate to store memory of its os to store filed & attribute.
object ,when created first store in heap area.but it's field value is store in stack area.
we can store the value to heap area by call by reference method.

Whenever the object is created by the JVM, the object is allocated in the free space called heap. The object reference placed in the frame, which is the smallest part in the stack. (stack is built up of many smallest frames). (frame is the smallest memory in the stack).

JVM allocate the object in to heap and takes memory form OS
